一、什麼是“變坐標作圖”普通作圖所用的方格紙(意匠紙),是均匀分度的,在這种紙上,任一點离坐標原點(原點的坐標值0)的距離等於該點的坐標值和一個被稱為“分度模數”的常數的乘積,這種分度均匀的坐標,稱為“等距坐標”;通常用以作為量具的直尺上的刻度,那是這一類型。“變坐標”也稱“變距坐標”或“不等距坐標”,它的意義和這相反;在變坐標的圖紙上,分度是不均匀的:如果坐標值為1的點離開尺度的原點為3公厘;那在均匀分度的尺上,坐標价為2的點就該離原點6公厘;而在“變坐標”上,則没有這樣的規律可循,計算尺上的許多尺度,就常是這種類型。“變坐標”常常用來作圖表,在圖解法和圖算法的領域裏,它的應用很廣。一般應用變坐標作圖的場合,大致有三: 1.把常用的公式或經驗數據,作成變坐標
First, what is the “variogram drawing”? The normal paper used for drawing (square paper) is evenly indexed. On this paper, the distance from any point to the origin of coordinates (the coordinate value of the origin 0). Equal to the product of the coordinate value of the point and a constant called a “division modulus”, this uniform indexing coordinate is called “equidistant coordinate”; the scale on the ruler, which is usually used as a measuring tool, That is the type. “Variable Coordinates” is also called “Variable Coordinates” or “Not Equidistant Coordinates”. Its meaning is opposite to this; in the drawing of variable coordinates, the graduations are not uniform: if the coordinate value is 1, the point left the scale The origin is 3 mm; on a ruler with a uniform division, the point with a coordinate price of 2 should be 6 mm from the origin; and on the “variable coordinates”, there is no such rule to follow. Many scales are often of this type. The “variable coordinates” are often used to make charts. In the field of graphic methods and graph algorithms, it is widely used. Generally, when using variable-coordinates mapping, there are roughly three: 1. Make commonly used formulas or empirical data as variable coordinates.
